AdTech is an enterprise specialized in new material development and high precision online Aluminium Purification Treatment Equipment production since 2012, got positive feedback from the domestic and overseas markets. During the smelting process of aluminum and its alloys, there are oxidized inclusions (Al2O3) and hydrogen, which affect the melt particles, resulting in ingot gas bubbles, […]

Purifying molten aluminum outside the furnace through ceramic foam filter plates is an effective way to improve the cleanliness of molten aluminum. The ceramic foam filtration process can effectively remove various inclusions in the aluminum liquid with a fineness of micrometers, reduce the influence of inclusions on the quality of cast-rolled billets, and provide a […]

According to the cause of porosity in cast aluminum alloy, in order to prevent porosity in the aluminium alloy casting and refining process, it is possible to reduce the porosity in aluminum alloy castings by degassing and removing impurities. Granular flux is widely used to degas and remove inclusions. Aluminium Alloy Refining Process Prevent water molecules […]

The main defects of cast aluminum alloy: pores and slag inclusion, which are caused by solid particles such as gas and oxides remaining in the alloy. Therefore, in order to obtain high-quality melt, it is not only necessary to select the correct and reasonable smelting process, but also the flux refining and purification treatment of […]

Due to the relatively high content of alkali metals in the electrolytic aluminium, the aluminium liquid refining process needs to be strengthened. Use 5%~10% chlorine and argon to refine the furnace for no less than 15 minutes, or use high-quality refining agents multiple times. In addition, the smelting furnace process needs to be optimized. After […]

According to the principle of aluminum refining agent purification, the refining agent generates tiny gas bubbles through a chemical reaction in the aluminum melt. When these gas pools float up, hydrogen and non-metallic inclusions are taken out of the surface of the aluminum melt. At the same time, the non-metallic inclusions are wetted by the […]

When high-purity argon is used as the refining gas for molten aluminum alloy refining, the argon should be preheated in advance to improve the refining effect. Using preheated argon for refining can produce high temperature and fine and uniform “hot bubbles”, with a small temperature difference with the melt, which is conducive to the stability […]

To produce high-quality double zero aluminum foil, it is necessary to strictly control the residual hydrogen content in the aluminum foil blank. Aluminum melt purification process can reduce the formed bubbles, and reduce its influence on the processing performance of the aluminum foil. In the current industrial production process, the hydrogen content of aluminum foil […]

The tabletop refractory product is made by placing aluminum-silicon material in a mold, uses molten high-silica 140 material. It is used to distribute molten metal to mold positions in billet casting tables, performs molten metal casting in cooperation with other casting equipment, such as thimbles, transition plates. In the air-slip casting table, close casting is […]

According to the different degassing mechanisms, the molten metal degassing refining method of aluminum alloy melt can be divided into partial pressure difference degassing, compound degassing, electrolytic degassing, etc. The partial pressure difference molten metal degassing refining method is to place the gas-dissolved metal in a vacuum with a small hydrogen partial pressure, or to introduce […]
